Dear R users, A have a dataframe (matrix) with two collumns (plot, and diameter (d)). I want all diameters values for different combination of plots. For example I want all d values for all posible combination, 100C2 (all d values for plot 1 with all d values in the plot 2.......with all d values from plot 1 with all d values from plot 100, ...... with all d values from plot 99 with all d values from plot 100). Total 4950 values of diameter (d). Thank you very much! structure(list(plot = c(1L, 1L, 1L, 1L, 2L, 2L, 3L, 3L, 3L, 3L, 4L, 4L, 4L, 5L, 5L, 5L, 5L, 6L, 6L, 7L, 7L, 7L, 7L, 8L, 9L, 9L, 10L, 10L, 10L, 11L, 11L, 12L, 12L, 12L, 12L, 13L, 13L, 13L, 13L, 13L, 14L, 14L, 14L, 14L, 15L, 15L, 15L, 15L, 15L, 15L, 16L, 16L, 16L, 16L, 16L, 17L, 17L, 17L, 18L, 18L, 18L, 19L, 19L, 19L, 19L, 20L, 20L, 20L, 21L, 22L, 22L, 22L, 23L, 23L, 23L, 23L, 23L, 24L, 24L, 25L, 25L, 25L, 25L, 26L, 26L, 26L, 26L, 26L, 27L, 27L, 27L, 27L, 27L, 28L, 28L, 28L, 28L, 29L, 29L, 29L, 30L, 30L, 30L, 30L, 32L, 32L, 32L, 32L, 33L, 34L, 34L, 34L, 35L, 36L, 36L, 36L, 36L, 37L, 37L, 37L, 38L, 38L, 38L, 38L, 38L, 38L, 39L, 39L, 39L, 39L, 39L, 39L, 40L, 40L, 40L, 41L, 41L, 42L, 42L, 42L, 42L, 42L, 42L, 42L, 43L, 44L, 44L, 44L, 45L, 45L, 46L, 46L, 47L, 48L, 48L, 48L, 49L, 50L, 50L, 50L, 50L, 50L, 50L, 51L, 51L, 52L, 52L, 53L, 53L, 53L, 54L, 54L, 54L, 54L, 55L, 56L, 56L, 57L, 57L, 57L, 58L, 58L, 58L, 59L, 60L, 60L, 60L, 61L, 61L, 62L, 62L, 63L, 63L, 64L, 64L, 64L, 65L, 65L, 66L, 66L, 66L, 67L, 67L, 67L, 68L, 68L, 68L, 69L, 69L, 70L, 70L, 71L, 71L, 73L, 73L, 73L, 73L, 74L, 74L, 74L, 74L, 75L, 75L, 75L, 75L, 76L, 76L, 76L, 76L, 78L, 78L, 78L, 79L, 79L, 80L, 80L, 81L, 81L, 81L, 81L, 82L, 82L, 82L, 83L, 83L, 83L, 84L, 85L, 85L, 85L, 87L, 87L, 87L, 87L, 87L, 87L, 88L, 88L, 88L, 88L, 89L, 89L, 90L, 91L, 91L, 91L, 91L, 91L, 92L, 93L, 93L, 94L, 95L, 95L, 95L, 95L, 96L, 96L, 96L, 97L, 97L, 98L, 98L, 98L, 98L, 99L, 100L, 100L, 100L, 100L, 100L), d = c(15, 27.5, 10.5, 12.25, 14, 32.5, 80, 49.5, 15.25, 13.5, 12.25, 12, 72.5, 68.5, 12, 9.25, 12.75, 13.5, 28, 38, 10.25, 62.5, 73.5, 61.5, 54.5, 40, 24.25, 43, 13, 20.75, 23.25, 25.5, 7.25, 11.25, 60.5, 11.25, 8, 11, 93.25, 8.75, 10.5, 35, 19, 79, 60.5, 64.5, 53.75, 8.75, 9.75, 9.5, 12.5, 21, 10, 46.75, 48.5, 77.5, 23.75, 60, 11.5, 13.25, 13.75, 76.25, 12.5, 8, 70, 47.75, 52.25, 49.25, 11.25, 12.5, 15.25, 20.25, 19.25, 20.5, 13.5, 86, 23, 10.5, 20.25, 27.75, 11.25, 32.5, 28.25, 12.5, 14.75, 83, 19.25, 14.25, 21.5, 26.75, 11.25, 56, 19.75, 55.25, 10, 16.75, 12.5, 19.75, 13, 19.25, 9.75, 75, 12.5, 11.25, 14.5, 69.5, 13.75, 15.75, 63.75, 18.75, 9.25, 68, 29, 17.75, 15, 27.25, 10.25, 13.5, 68.25, 9.25, 13, 16.75, 36.5, 11.25, 87.25, 69.75, 66.25, 15.25, 14.75, 9, 15.75, 17.75, 82, 13.25, 20, 82.5, 86.5, 7.75, 14.5, 9.25, 95.5, 8.25, 12, 13.5, 16.5, 69, 15.5, 12, 42, 79.5, 40.75, 13.25, 10, 76.5, 10.75, 16.5, 12.5, 60.25, 11.25, 17, 63.25, 96, 14.25, 49.5, 56.5, 18, 84.25, 69.5, 12, 64.75, 48.5, 8.25, 29, 68, 7.25, 79.75, 55, 75.5, 60.75, 57.5, 61, 15.25, 69, 52.25, 98, 13.25, 14.25, 60.75, 14.25, 12.25, 56.5, 18, 76.25, 20.75, 10.5, 63.25, 12.5, 11.75, 84.5, 33.25, 77.75, 71.5, 11.5, 13.5, 19, 31.5, 27.25, 21, 13.25, 12.5, 31.75, 22, 20, 58.5, 40.5, 62, 85.5, 11.5, 12, 10.5, 80.75, 55.5, 87, 42.5, 70.5, 9.25, 56, 73.75, 12.75, 11, 59, 18.75, 10.75, 81, 14, 33.5, 13.25, 69.25, 8.75, 14.5, 63, 89.25, 73.75, 48.25, 58, 11.5, 17.25, 12.75, 10, 11.5, 15.25, 93.5, 14.5, 83.75, 9.75, 95, 13.5, 16.25, 8.5, 8.5, 70, 9.75, 72.5, 71.5, 9.5, 83, 43.75, 51, 55.25, 75.5, 61, 53.75, 60, 12.25, 47, 13.75, 86.5, 14.5, 10, 9.75, 12, 13.75, 31.75, 64.75, 13.75, 83.5, 45.5, 67, 84.5, 57.5, 46)), .Names = c("plot", "d"), class = "data.frame", row.names = c(NA, -291L)) -- --- Catalin-Constantin ROIBU Forestry engineer, PhD Forestry Faculty of Suceava Str.

Thank you very much! structure(list(plot = c(1L, 1L, 1L, 1L, 2L, 2L, 3L, 3L, 3L, 3L, 4L, 4L, 4L, 5L, 5L, 5L, 5L, 6L, 6L, 7L, 7L, 7L, 7L, 8L, 9L, 9L, 10L, 10L, 10L, 11L, 11L, 12L, 12L, 12L, 12L, 13L, 13L, 13L, 13L, 13L, 14L, 14L, 14L, 14L, 15L, 15L, 15L, 15L, 15L, 15L, 16L, 16L, 16L, 16L, 16L, 17L, 17L, 17L, 18L, 18L, 18L, 19L, 19L, 19L, 19L, 20L, 20L, 20L, 21L, 22L, 22L, 22L, 23L, 23L, 23L, 23L, 23L, 24L, 24L, 25L, 25L, 25L, 25L, 26L, 26L, 26L, 26L, 26L, 27L, 27L, 27L, 27L, 27L, 28L, 28L, 28L, 28L, 29L, 29L, 29L, 30L, 30L, 30L, 30L, 32L, 32L, 32L, 32L, 33L, 34L, 34L, 34L, 35L, 36L, 36L, 36L, 36L, 37L, 37L, 37L, 38L, 38L, 38L, 38L, 38L, 38L, 39L, 39L, 39L, 39L, 39L, 39L, 40L, 40L, 40L, 41L, 41L, 42L, 42L, 42L, 42L, 42L, 42L, 42L, 43L, 44L, 44L, 44L, 45L, 45L, 46L, 46L, 47L, 48L, 48L, 48L, 49L, 50L, 50L, 50L, 50L, 50L, 50L, 51L, 51L, 52L, 52L, 53L, 53L, 53L, 54L, 54L, 54L, 54L, 55L, 56L, 56L, 57L, 57L, 57L, 58L, 58L, 58L, 59L, 60L, 60L, 60L, 61L, 61L, 62L, 62L, 63L, 63L, 64L, 64L, 64L, 65L, 65L, 66L, 66L, 66L, 67L, 67L, 67L, 68L, 68L, 68L, 69L, 69L, 70L, 70L, 71L, 71L, 73L, 73L, 73L, 73L, 74L, 74L, 74L, 74L, 75L, 75L, 75L, 75L, 76L, 76L, 76L, 76L, 78L, 78L, 78L, 79L, 79L, 80L, 80L, 81L, 81L, 81L, 81L, 82L, 82L, 82L, 83L, 83L, 83L, 84L, 85L, 85L, 85L, 87L, 87L, 87L, 87L, 87L, 87L, 88L, 88L, 88L, 88L, 89L, 89L, 90L, 91L, 91L, 91L, 91L, 91L, 92L, 93L, 93L, 94L, 95L, 95L, 95L, 95L, 96L, 96L, 96L, 97L, 97L, 98L, 98L, 98L, 98L, 99L, 100L, 100L, 100L, 100L, 100L), d = c(15, 27.5, 10.5, 12.25, 14, 32.5, 80, 49.5, 15.25, 13.5, 12.25, 12, 72.5, 68.5, 12, 9.25, 12.75, 13.5, 28, 38, 10.25, 62.5, 73.5, 61.5, 54.5, 40, 24.25, 43, 13, 20.75, 23.25, 25.5, 7.25, 11.25, 60.5, 11.25, 8, 11, 93.25, 8.75, 10.5, 35, 19, 79, 60.5, 64.5, 53.75, 8.75, 9.75, 9.5, 12.5, 21, 10, 46.75, 48.5, 77.5, 23.75, 60, 11.5, 13.25, 13.75, 76.25, 12.5, 8, 70, 47.75, 52.25, 49.25, 11.25, 12.5, 15.25, 20.25, 19.25, 20.5, 13.5, 86, 23, 10.5, 20.25, 27.75, 11.25, 32.5, 28.25, 12.5, 14.75, 83, 19.25, 14.25, 21.5, 26.75, 11.25, 56, 19.75, 55.25, 10, 16.75, 12.5, 19.75, 13, 19.25, 9.75, 75, 12.5, 11.25, 14.5, 69.5, 13.75, 15.75, 63.75, 18.75, 9.25, 68, 29, 17.75, 15, 27.25, 10.25, 13.5, 68.25, 9.25, 13, 16.75, 36.5, 11.25, 87.25, 69.75, 66.25, 15.25, 14.75, 9, 15.75, 17.75, 82, 13.25, 20, 82.5, 86.5, 7.75, 14.5, 9.25, 95.5, 8.25, 12, 13.5, 16.5, 69, 15.5, 12, 42, 79.5, 40.75, 13.25, 10, 76.5, 10.75, 16.5, 12.5, 60.25, 11.25, 17, 63.25, 96, 14.25, 49.5, 56.5, 18, 84.25, 69.5, 12, 64.75, 48.5, 8.25, 29, 68, 7.25, 79.75, 55, 75.5, 60.75, 57.5, 61, 15.25, 69, 52.25, 98, 13.25, 14.25, 60.75, 14.25, 12.25, 56.5, 18, 76.25, 20.75, 10.5, 63.25, 12.5, 11.75, 84.5, 33.25, 77.75, 71.5, 11.5, 13.5, 19, 31.5, 27.25, 21, 13.25, 12.5, 31.75, 22, 20, 58.5, 40.5, 62, 85.5, 11.5, 12, 10.5, 80.75, 55.5, 87, 42.5, 70.5, 9.25, 56, 73.75, 12.75, 11, 59, 18.75, 10.75, 81, 14, 33.5, 13.25, 69.25, 8.75, 14.5, 63, 89.25, 73.75, 48.25, 58, 11.5, 17.25, 12.75, 10, 11.5, 15.25, 93.5, 14.5, 83.75, 9.75, 95, 13.5, 16.25, 8.5, 8.5, 70, 9.75, 72.5, 71.5, 9.5, 83, 43.75, 51, 55.25, 75.5, 61, 53.75, 60, 12.25, 47, 13.75, 86.5, 14.5, 10, 9.75, 12, 13.75, 31.75, 64.75, 13.75, 83.5, 45.5, 67, 84.5, 57.5, 46)), .Names = c("plot", "d"), class = "data.frame", row.names = c(NA, -291L)) -- --- Catalin-Constantin ROIBU Forestry engineer, PhD Forestry Faculty of Suceava Str.
